lsoLii PROTECTOR,"

taining, a full, clear, and exact description,

reference being had to the accompanying drawings, forming a part hereof.

My invention relates to improvementsin sole protectors and has for itsprimary object the construction of a protector which may be driven intothe soleor other part of the shoe and it willautomatically clinch Withinthe material and will not pass through the sole and not require anysubsequent clinching.

This invention is an improvement on the sole protector previouslypatented by meen July 15, 1920, Patent No. 1310050.

In the drawings:

Fig. l is an enlarged side elevation of my protector.

Fig. 2 is a sectional elevation of the same showing the same applied tothe sole of the shoe, a portion of the shoe sole being broken awa Fig. 3is a bottom plan view of the saine.

Fig. 4 is a topl plan View of the saine.

Referring to the drawings, 5 is a combined driving head and wearingplate, which is substantially elliptical and provided with prongs 6formed at substantially right angles with the head 5.' The prongs 6 arearranged at each end of the driving head 5 and are provided with outercurved faces 7 and with inner straight plain faces 8; the l outer curvedfaces and the inner straight` plain faces merging together and forming`points 9. The side edges of the prongs are parallel and the prongs areof uniform width from the head or wearing plate to lin this portion isvreduced, thus lessening the resistance offered in seating` the pro- Theleather, Whichj is compressed by the entering prong, thus tector in theleather.

tion of the prong tightly/ gripping the latter and forming a close jointon the'exterior surface of the prong.` It will also be ob-` l i servedthat the prongs are bent withk sharp inner angles relative to the heador" wearing plate, and that the thickness of the prongs at this point,which may be designated` as j at 10, is less than the materialout ofwhich the protector is formed vand hence less than the thicknessof thewear plate or of the portion of the prong just beyond the neck 10.

This assists-in the easy bending or clinchingof the prong. Thisrelatively thin porf tion is purposely designed in making the protectorand arises from making a sharp angle as at 11 on the inside faces of thef .prongs and rounding the outer surfaces of the prongs adjacent thedriving header wearing plate.

Having fully described my invention,

what I claim is: Y

1. A sole protector comprising a `driving yhead and wear plate having aprong formed integral with each end thereof, lsaid prongs extending withsharp inside angles-"from the plate and having plane, smooth, straightinner faces and the outer faces lof said prongs composed of compositecurved surfaces, said prongs being of slightly `less thickness at theircorners than at a distance from the corners.

2. A sole protector comprisinga driving 'head and wear plate having aprong Aformed integral with each end thereof, said prongs being arrangedwith sharp inside angles to the plate and having smooth, straight, innersurfaces and' outer composite curved surfaces, the surface adjacentthepoint of the prongs being struck from an are of a circle whose radiusisy greater than the surface adjacent the plate, the formation of.`
